To all 'whom z't may concern.'

Be it known that I, MAX F. GARLIN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Marginal Folding Devices; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

Great difculty has been experienced heretofore in properly folding over the margin of a piece of fabric so as to permit the fabric piece to be readily stitched in place, particularly in the case of pockets for garments wherein the piece of fabric is sewed to the garment through the folded margin of the fabric.

This invention relates to a machine into which the piece of fabric, which has been cut according to the pattern, is placed, and when operated upon by the machine has its margin folded and creased inwardly, so that attachment of the piece of fabric to a garment by stitching through said folded margin becomes a simple and convenient operation.

It is an object of this invention to construct a machine for folding and creasing the margin of a piece of fabric according to a predetermined shape wherein the parts are adjustable for operation upon pieces of fabric of different size, though similar in shape.

It is also an object of this invention to construct a pocket fabric marginal folding and creasing machine wherein a presser plate is actuated downwardly between folder bars to operate in conjunction therewith, folding the margin of the fabric inwardly while slightly heating the same during the operation so that a more or less permanent crease is made in the fabric to define the folded margin to facilitate attachment of the fabric to a garment by stitching through said folded margin.

It is furthermore an important object of this invention to construct a pressing machine adapted to fold the margin of a piece of fabric of predetermined shape inwardly` and crease the same by a single pressing operation of the parts of the mechanism.

It is finally an object of this invention to construct an improved type of folding, creasing and pressing machine with the parts so arranged as to permit easy access thereinto to position and remove a piece of fabric in and from the machine, and with the parts adjustable to accommodate and operate upon pieces of fabric of different size.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

As shown in the drawings:

The frame ofthe machine consists of a pair of uprights l and 2, respectively, reinforced and joined by a transverse member 3, and with a table 4, supported on and be tween said uprights. Bearings 5., are secured at the upper ends of the uprights l and 2,

and journaled therein is a driving shaft 6,

provided with a disk 7, secured thereon, having a cam groove afforded between ridges 8, formed on said disk. Connected on one end of said shaft 6, is an automatically acting clutch denoted as a whole by the reference numeral 9, which acts to disengage here.

For the purpose of actuating said clutch 9, a foot lever 11, is provided, mounted on the floor adjacent the base of the frame member 2, and is connected by means of a long actuating rod 12, to said clutch. Slid-y able vertically through a guide aperture provided in the cross frame member 3, is a lpresser plate shaft or rod 13, and journaled horizontally on one side at the upper' end thereof is a roller 14, adapted to track in the cam groove between the ridges 3, on said disk 7. Secured on or integral with the lower end of the vertical presser shaft 13, are four slotted spider arms 15, reinforced at their inner ends by a web 16. Mounted beneath the arms 15, is a presser plate, the outline of which is substantially the same as that of the piece of fabric to be folded and creased, said presser plate consisting of a base plate member of wood or metal, denoted by the reference numeral 17, and with a thin sheet or plate of metal 13,

secured therebeneath, with the margin there- Y of projecting beyond the edge of the base member 17, almost entirely therearound, as clearly shown in Figs. 3, 3 and 9. Said presser plate 17-18, is yieldably connected beneath the arms 15, of the spider, in the following manner. For this purpose bolts 19, are threaded into the top plate 17, and extend slidably through bushings 20, held clamped in the slots in said arms 15, by small collars 21, and are further provided with nuts 22, which hold the bolts 19, against withdrawal through said bushings 20.

loiled around each of said bolts 19, is a spring 23,v one end of which bears upon the upper-surface of the plate 17, and the other end of which bears beneath the lower end of the bushing 20, said springs acting norv mally to impel and hold the 'presser plate 17-18, downwardly away from the supporting spider arms 15. Resilient presser feet are also provided at the outer ends of the arms 15, and for this purpose, as shown in detail in Fig. 12, a bushing 24, is held clamped in the slot of each of the arms 15, by a threaded collar 25, and slidable through said bushing is a rod or bolt 26, having a fiat bearing foot 27, on its lower end, on the upper surface of which seats a coiled compression spring '28, normally impelling the same downwardly, and a nut 29, is threaded on the upper end of said bolt to retain the same from withdrawal through said bushing by the stress of said spring.

Yieldably mounted upon the table 4, conforming to the outline of Iand partly surrounding the presser plate 17-18, are folding and creasing devices comprising curved bars 30, which are cored out at the points 31, in their upper surface to receive water poured therein for cooling purposes. As clearly shown in Fig. 13, the inner side of each of said bars 30, is cut away to afford a continuous tapered edge 32, adapted to engage beneath the margin of the fabric and crease the same upwardly around the outer edge of the presser plate during the operation of the device. rllhe presser feet 27, before described, adjustably mounted upon the spider' arms 15, are so disposed as to contact and bear upon the bars 30,'to force the same downwardly, and said bars 30, in turn are yieldably as well as slidably supported in the following manner.

For this purpose grooved bosses 33, are formed on the under surface of the table 4, as clearly shown in Figs. 6 and 10, and slidable in the groove of each of said bosses are fiat bars or links 34, one of which is shown in Fig. 14, each having a plurality of apertures 35, near one end thereof to receive threaded thereinto the lower end of an upright bolt 36, as shown in Fig. 10. Said upright bolts 36, extend slidably through the respective bars 30, and are adapted to slide in slots provided therefor in the table 4, directly above said bosses 33, said slots being denoted. by the reference numeral 37, as shown in Figs. 7, 8, and 9. Coiled around each of said upright bolts 36, and seated in a recess provided on the under side of said respective bars 30, are springs 33, which bear upon the upper surface of the table 4, thus normally maintaining said curved bars 30, elevated therefrom. Slots 39, parallel to said slots 37 are also provided in the table 4, as clearly shown in Fig. 6, and sliding in each is the rectangular shaped end of one of two guide bolts 40, which extend slidably through the bars 30, and compression springs 41, are coiled therearound, bearing upwardly beneath the bars 30, and downwardly upon the table 4, to normally maintain said bars 30, elevated therefrom. For the purpose of drawing' said curved bar 30, slightly inwardly at the proper time during the operation of the machine, a disk 42, is pivotally mounted upon the under surface of the table 4, and is provided with similar cam slots 43, which are slightly angled, as clearly shown in Fig. 6, and journaled on the inner ends of each ofthe links or bars 34, are rollers 44, which lit into said respective cam slots 43, so that by an oscillation of said disk 42, said links 34, are caused to slide in the recesses therefor in the bosses 38. Mechanisms are provided driven from the drive shaft t3, for oscillating said disk 42. YFor this purpose, a small bevel pinion 45, is secured upon the end of the shaft 6, meshing with a bevel pinion 46, secured upon the end of an upright shaft 47 which is, journaled in bearings 48, secured upon the frame member 1. On the lower end of said upright shaft is a disk 49, which has pivotally connected thereto a link 50, which is in turn pivoted on said disk 42. Mounted beneath the disk 42, and connecting link 50, is an apertured ring pipe 51, through which steam is admitted, heating and rendering the atmosphere more or less moist in the eld of operation of the machine, so that the folding and creasing of the fabric imparts more or less permanency to the fold or crease made therein.

r[he operation is as follows:

r[he construction of the driving disk 7, is such that the cam groove afforded between the ridges 8, with each revolution of the disk 7, first imparts a descending movement to the presser plate, holding the same slightly spaced above the table 4, for an instant, and then thrusting the same downwardly and holding the same thereagainst for a certain interval, then elevating and holding the presser plate slightly spaced above the fabric and then withdrawing the presser plate to initial elevating position. rlhe pressing or pressure part of the operation is performed during the time that the roller 14, on the upper end of the shaft or rod 18, is in the arc shaped and outwardly offset portion 52, of the cam groove between the ridges 8. Also driven simultaneously with the presser plate at times for proper co-action therewith, are the folder and creasing bars 30, which move inwardly guided by the' respective slots 37 and 39, such that the tapered edges 32, which engage beneath the fabric, denoted by the reference numeral 58, and shown in Figs. 8, and 9, folds the fabric over the outer margin of the plate 18, from the position shown in Fig. 8, to that shown in Fig. 9. The pressure is transmitted yieldably to said bars 30, from the spider arms 15, with a final downward movement of the upright 13, through the presser feet 27.

The inward movement of said bars 30, is effected by the oscillation of the disk 42, driven from and properly timed with respect to the shaft 6, through the shaft 47, and link 50. An oscillation in one direction of said disk 42, first draws said hars 30, inwardly, so that the tapered edges 32, thereof, engage beneath the margin of the fabric 553, but above the plate 18, as shown in Fig. 8, and then farther inwardly, so as to fold the fabric over the sheet 18, and beneath said tapered edges 32, as shown in Fig. 9, so that the descending spider arms 15, will impart pressure upon the inwardly folded margin of the fabric through the bars 30.

Immediately after the pressure is released by upward movement of the spider arms 1.5, the bars 30, move upwardly under the stress of their supporting springs 38, and the reverse oscillation of said disk 42, now takes place, so that the pressure bars 30, are moved outwardly, and after the presser plate 17-18, is elevated away, the fabric operated upon may be removed. The presser plate 17-18, may be detached and replaced by one of smaller area and the bars 30, may be moved inwardly to correspond thereto for operation on pieces of fabric of different size.

1 am aware that various details of construction may be varied through a wide range without departing from the principles of this invention, and l therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.
